Official infrastructure, real teamwork, visible rules

Your number, your account

You connect your number with your own Meta account through Meta's signup flow. The WhatsApp Business account is in your name, and the UPPU team enables the channel for your workspace.

The whole team on one screen

Assignment routes each conversation to the right agent. Agents see customers' numbers masked, and the history stays with your company, not on staff phones.

The rules are visible

The 24-hour window is counted by Meta's clock and shown in the conversation. Template approval statuses and a 9-item channel checklist are in the panel.

Setup

How you connect WhatsApp

You connect your number in Meta's own window, and the panel shows the channel's status at every step.

    Sign up on app.uppu.net and create your workspace; 14 days free, no credit card. The inbox interface is in Turkish today.

  2. Our team enables WhatsApp

Content

What you can send and receive

What arrives and what you can send. Agents send text and files from the inbox; messages with buttons and lists, reactions, location, quoted replies and templates go from your system through the API. The status of every outgoing message shows in the conversation.

Content types on WhatsApp

TextYesYesYes
Images, video, audio and documentsYesOne file per replyYes
Messages with buttons and listsYesNoYes
ReactionsYesNoYes
Reply context (quotes)YesNoYes
LocationYesNoYes
Approved templatesNot applicableNoYes
StickersYesNoNo

Sending contact cards and stickers: in a later version. Incoming media is kept for 90 days, up to 25 MB per file.

Sent, delivered and read statuses show for every outgoing message, and if Meta rejects a message you see an explanation of the error (in Turkish today).

The 24-hour window

The 24-hour window and templates, briefly

Meta's rules decide when and how you can write to a customer on WhatsApp, and UPPU shows them on screen.

  • When a customer writes to you, a 24-hour customer service window opens. During it you send service messages (free-form replies within 24 hours of the customer's message); the window is counted by Meta's clock.
  • Once the window closes, you can only write with an approved template: a utility or a marketing template.
  • Marketing templates need a recorded consent; anyone who writes STOP has their consent withdrawn.
  • You create templates in the panel; today you send them through the API.

Comparison

WhatsApp Business app or UPPU?

The app can be enough for a small team replying from a phone. The difference shows once the team grows or your systems get involved.

Official platform vs QR-based tools

Tools that link a phone's WhatsApp session by QR code look easy, but WhatsApp's own terms prohibit that kind of use.

All questions
What language is the interface in?

The inbox interface is in Turkish today. The live chat widget your visitors see speaks Turkish and English, and API error messages come in either language. Talk to us and we'll walk you through it.

Is it the official WhatsApp platform?

Yes. UPPU runs on Meta's official WhatsApp Business Platform (Cloud API). You connect your own WhatsApp Business account and number through Meta's signup flow, and the UPPU team enables WhatsApp for your workspace. It is not the same as tools that link a phone session by scanning a QR code.

Could my number get blocked?

No platform can rule that out, but UPPU runs on Meta's official WhatsApp Business Platform. Meta usually restricts numbers that break its rules: unsolicited bulk messages, content people report, or low quality. In UPPU, marketing templates need a recorded consent and anyone who writes STOP has their consent withdrawn, and you see delivery statuses and explanations of Meta's errors in the panel (in Turkish today). Our comparison of the official API and QR tools sets out how unofficial tools differ.

Can I use my own number? Will it still work in the phone app?

Yes, the number and the account are yours. Today a number connected to UPPU can't be used in the WhatsApp Business app on your phone at the same time; you can also start with a new number.

Who pays Meta's fees, and how?

WhatsApp message fees aren't included in UPPU's price; Meta charges them separately. The fee depends on the message category and the recipient's country code, and since 1 October 2026 the first 1,000 service messages per business number each month are free. We explain the calculation on the pricing page.

What is the 24-hour window?

When a customer writes to you on WhatsApp, a 24-hour customer service window opens and you can reply freely during it with service messages. It's counted by Meta's clock from the customer's last message. Once it closes you can only write with a template Meta has approved; UPPU shows the time left above the conversation.

Can I send bulk messages or campaigns?

There is no campaign or bulk-send screen in the panel. You can send approved templates from your own system through the API, within Meta's messaging limits and consent rules; sends are limited to 20 per second per key, and marketing templates need a recorded consent. Consent duties for commercial messages, such as Türkiye's İYS registry, stay with you.

How long does WhatsApp setup take?

First the UPPU team enables WhatsApp for your workspace: after you sign up, just email info@uppu.net with your company name. Then you connect your number with your own Meta account in Meta's signup window. The display-name review and, for higher messaging limits, business verification are Meta's own processes, and Meta sets their timing. The channel checklist shows where each step stands.

Does it work with click-to-WhatsApp ads?

Yes. Messages that start from those ads land in your inbox, and your team answers from the same screen. While Meta's free entry window is open, the messages in that conversation are free; Meta sets the terms, and the details are on the pricing page. You run your ads in Meta yourself; UPPU doesn't manage ads.
